Interface PortConstraintOptimizer

All Known Implementing Classes:

AbstractPortConstraintOptimizer, PCListOptimizer

public interface PortConstraintOptimizer

This interface serves as a callback for HierarchicLayouter after the layering and sequencing phases. Implementations of this interface may modify the port constraints (PortConstraint) information via ItemFactory.setTemporaryPortConstraint(y.base.Edge, boolean, y.layout.PortConstraint).

Method Summary

void	optimizeAfterLayering(LayoutGraph graph, Layers layers, LayoutDataProvider ldp, ItemFactory itemFactory) Called after the layering information has been determined.
void	optimizeAfterSequencing(LayoutGraph graph, Layers layers, LayoutDataProvider ldp, ItemFactory itemFactory) Called after the sequence of the nodes has been determined.

Method Detail

optimizeAfterLayering

void optimizeAfterLayering(LayoutGraph graph,
                           Layers layers,
                           LayoutDataProvider ldp,
                           ItemFactory itemFactory)

Called after the layering information has been determined. This method can be used to assign new temporary port constraints for the next phases of the algorithm.

Parameters:

graph - the graph to work on

layers - the layering information

ldp - the implementation which provides access to the NodeData and EdgeData instances

itemFactory - the factory to set the temporary port constraints with

optimizeAfterSequencing

void optimizeAfterSequencing(LayoutGraph graph,
                             Layers layers,
                             LayoutDataProvider ldp,
                             ItemFactory itemFactory)

Called after the sequence of the nodes has been determined. This method can be used to assign new temporary port constraints for the next phases of the algorithm.

Parameters:

graph - the graph to work on

layers - the layering information

ldp - the implementation which provides access to the NodeData and EdgeData instances

itemFactory - the factory to set the temporary port constraints with
